Absolution is a theological term for the forgiveness imparted by ordained Christian priests and experienced by Christian penitents. It is a universal feature of the historic churches of Christendom, although the theology and the practice of absolution vary between Christian denominations.

An Evangelical Lutheran confessional in Luther Church (Helsinki, Finland); the Augsburg Confession divides repentance into two parts: "One is contrition, that is, terrors smiting the conscience through the knowledge of sin; the other is faith, which is born of the Gospel, or of absolution, and believes that for Christ's sake, sins are forgiven, comforts the conscience, and delivers it from terrors."
Penance is any act or a set of actions done out of repentance for sins committed, as well as an alternate name for the Catholic, Lutheran, Eastern Orthodox, and Oriental Orthodox sacrament of Reconciliation or Confession. It also plays a part in confession among Anglicans and Methodists, in which it is a rite, as well as among other Protestants.
